LE LATHE R-S'IAKING-MACHINE TABLE I?! where "ii -.":'.'o: e,' conce n: iknown that I, .l iianni l tlnoooiie, ot' the United States, residing inthe .L Yiilinington. county of New ".tle, to olTDelaware, have inventeda new and a. nil LeatherStaking Machine Table, of which the following aspecification. i

This invention relates to a machine for staking leatherand has for anobject to pro Ylde an operating table which may be readily moved out otthe way when t. is desired to repair or inspect the, opcra tinglnirts ofthe machine.

Ithas for a further iibjeot-to provide a staking machine with a breastroller on the working table, the position of which may be shifted atwill, thereby bringing. a large number ofworking-faces successively intoposition.

It further consists of othernovel features of construction, all aswill'be hereinatter fully set forth.

For the purpose ot'illustratiug my invention, I have shown in' theaccompanying drawings one form thereof which is at present. preferred byme. elll jftf the same has been tonndnin practice to give satisfactoryand reliable results, although it is to be understood. that the variousinstrumeutalities oil; which my invention consists can be vz'irionsly a;god and organized and that my invention is not limited to the precisearrangement and organization of these instrumentalities as herein shownand described.

and knives I) for scraping the leather during it will of course la"-undcrstood that these jaws :3 and 3 are mounted for reciprocationrelative to the machine frame 1 and thereby are drawn the customaryrollers 1 working and 7 over the length of thoskin.

(Sdesignates the work table npoir which the hide rests during the rccinria-ation-ol "the jaw member and inthe present instance this table 6 issecured to the frame 1 by nicans of apertured lugs T-loca ted on eachside of the frame and each adapt-ed to reccivea pin 8 secured to themain frame 1. It will be apparent that. by this arrange inenta pivotalconnection is provided be tween the frame 1 and the, table (i,'-whei 'i.ln.'

the latter may be swung as desired out of the normal operation position.J

9 designates a bracket secured in any well known manner to the mainframe 1 and car r ving thereon a support. for the table o. said supportin the present instance, consisting ot a bolt bracket 9, wherebyprovision is made the adjustment of the table (3'.

19 designates a bearing plate secured to the table ti and having thereinan aperture .13 to receive the head lit oi the bolt [0. wherebdisplacement between the cooperating parts is prevented. It will benoted that thc'hcad l lol the bolt 10 is sutiiciently large to furnish alateral extension for the purpose of engagement with a lock bolt losnitabl v mounted in brackets 16 of the plate 12 and provided with anoperatinghan'cl wheel- 17. Normally the bolt 15 is maintained in lockingengagement with. the, head it through the interposition of a-s'pring l8suitably positioned between the bracket; 18.

It will be apparent that when the table 13 is in the position shown inFig.1, that it. is

securely locked and can'only be raised by grasping the hand wheel 17 andwithdrawing the bolt 15 to release the; head 14. ()t course there willbe no interference with the jaw members in thus raising thetable ('i. asit will be recognized by'those skilled in the art that such a table isprovided with a ton gitudinal opening therein in which lhe jans :laud3'ai'c adapted to reciprocate.

1t) designates an end plate ex'teodiug transversel v-of the table t1,secured to huh it) threaded into a head 11. on the are end bearings 20and 21 adapted toreis mounted on a spindle24e formed, as'here ceive'andsupport for rotation relative there-1' to, the trunnions 22 of abreast'rolle'r 28. This roller .23 lspreferably formed of rub her orlike frlctlon"producing material and shown, as an integral portion ofthe trunnions 22. It will-be clear that in the opera tion of a stakingmachine this breast roller 23 performs an important function in that theoperator of the machine firmly pressesv :1 hide against this rollerduring the recipa rocatioh of the knives androllers and-the frictionsurface of. the roller 23 aids ma 'terially in preventing the skln'being 'forc1-.

, to operate and normally project into .the

path of the spindle 24: andwith which it cooperates by means of. aseries of perforations 2!) located atv intervals around the periphery ofthe spindle 2-1. .In order to maintain the plunger 28 in engagement withone of the perforations 29in the spindle 24 to lock' the latteragainstrotation, a coil spring 30is,

provided bearing'against the lug 25'on one side and'on the other againsta follower 31 fixedly secured tothe plunger 28.

It will be clear that when the plunger 28 is held by the sprin in one ofthe perforations 29 that the rolIer 23will be absolutely locked fromrotary movement and the operation' of thev machine correctly carriedout.

of the table 6 about the pivots 8, as it-is wellv It is well known thatin this type ofmachine' such breast rollers soon become worn, dueto theconstant pressure exerted against the face thereof and therefore itbecomes necesz, sary to shift the roller'to bring another portion of theperiphery into operative position. The customary method of shiftingthisroller involves theiitkingap'art of adjacent poi" tions of themachine in order jtogaccomplish the desired end, causing delay and theloss of use of the macliine during such shifting of the roller. By meansofmy novel im provement the machine is constantly in op:

eration and a new surface brought into usewhenever desired by simply, wthdrawing the bolt 28 from looking engagement with the spindle 24,whereupon the latter may be rotated as desired and the worn surfaceshifted out of the path of the skin.

Attention is further directed to the swinging known that frequently itbecomes necessary chine is running.

It will now be apparent that I have devised a. novel and usefulconstruction which embodies the features of advantage enumerated asdesirable ,in-the statement of the invention and the above descriptionandwhile I have in; the present instance shown and described thepreferred embodiment thereof, which has-been found in practice to givesatisfactory and reliable results, it

is'to be understood that the saine is susceptible of modification invarious particulars wlthout depart ng from the spirlt or scopeadvantages. I I I In'practiceI employ'a pin stop or abut-1 'ment whichis preferably locatedas indicated in Figs. 1 and 8, whereby the extentof upward movement of'the' table may be limited, said stop or abutment32 beingeither caston the frame 1 in practice 'or the same may i consistof a pin secured to the frame in any desired manner as will be evidentto those skilled in the art. i

Having thus described my injvei'i'tion, what of. the. invention orsacrificing any of its,
